1. INTRODUCTION
1.1 This manual
This manual contains minimum information that is necessary to properly install UT-4DR
communication interface within RACS 4 access control system and in other applications. Full
functional description of RACS 4 system and PR Master software is specified in following documents
which are available at www.roger.pl:
•Functional description of PRxx2 series controllers
•Functional description of PRxx1 series controllers
•PR Master User manual
2. DESCRIPTION AND SPECIFICATION
UT-4DR is Ethernet - RS485 interface enabling communication with PR series controllers of RACS 4
access control system through computer network. Additionally the interface is equipped with 4
universal Input/Output lines which can be managed using web browser or by means of Telnet
protocol. This feature gives possibility to use the device in other applications beyond RACS 4 system
as a remote I/O port managed through computer network. UT-4DR interface requires 12VDC power
supply and is installed in plastic enclosure dedicated to mounting on standard DIN 35mm rail.
Note: In case of use in RACS 4 system, the UT-4DR requires PR Master software in version 4.4.6 or
newer.
Note: It is not possible to use UT-4DR interface as a virtual serial port so it cannot be used for
firmware upgrade of PR series controllers connected to RS485 bus.
Note: It is not recommended to use UT-4DR interface for communication with discontinued PR201
and PR301 access controllers.

3.3 Power supply
UT-4DR interface requires 12VDC nominal power supply. The power should be connected to the
12V line and GND line. Additionally, the GND line can be used as reference potential for the RS485
bus and IO1..IO4 input lines. The power supply can be provided by means of power supply unit
(e.g. PS-15DR, PS20) which can be equipped with backup battery in order to ensure operation of
the interface in case of power failure.
Note: All devices connected to RS485 bus (including controllers) should have the same supply
minus (GND). In order to ensure this, all the GND terminals from various power supply units within
the system should be connected with each other using separate wire. Alternatively, the common
supply minus of the entire system can be earthed however only in one point.
3.4 Communication with interface
UT-4DR is equipped with 10BaseT Ethernet port which is used for communication with computer
and other devices/systems in LAN/WAN computer network.
Note: The operation of UT-4DR in dedicated LAN is guaranteed by Roger. Practical tests proved
that the interface can be also used in LAN, where multiple systems are operated as well as in WAN
but in such case UT-4DR functioning is not guaranteed by Roger due to number of possible and
unpredictable network conditions.
3.5 Communication of interface with controllers
UT-4DR is equipped with RS485 communication port which is used for communication with PR
series controllers. The RS485 bus consists of two signal lines A and B. In the RACS 4 system any
topology can be used (star, tree or any combination of them, except for loop) in order to connect
controllers in network (subsystem). The matching resistors (terminators) connected at the ends of
transmitting lines are not required. In most cases communication works with any cable type
(standard telephone cable, shielded or unshielded twisted pair etc.) but the recommended cable is
unshielded twisted pair (U/UTP cat.5). Shielded cables should be limited to installations subject to
strong electromagnetic interferences. The RS485 communication standard used in the RACS 4

UT-4DR User Manual Rev.G.doc

system guarantees proper communication in a distance of up to 1200 meters as well as high
resistance to interferences.
3.6 Input and output lines
UT-4DR is equipped with four IO1..IO4 general purpose lines which can be configured individually
as independent inputs or outputs. Each line can work with maximal voltage of 15VDC (in reference
to device’s power supply ground) both when operated as input or output. Input lines are triggered
by shorting them to ground (NO lines). Output lines in normal state represent high impedance while
in triggered state they short to ground. Maximal current switched by output lines is limited to 0.5A.
If this value is exceed, an internal overload protection is activated and then all output lines are
switched off until the overload problem is resolved. In overload state UT-4DR stops its normal
operation.

3.7 Installation guidelines
•Install devices in such way as to ensure easy access to screw terminals, jumpers and RST
button of the interface.
•All electric connections must be made with power supply switched off.
•All devices connected to the same communication bus (RS485) should be connected to the
same negative potential (GND). Therefore all GND terminals from various power supply units
used in the system should be connected with each other.
4. CONFIGURATION
4.1 Configuration with web browser
In order to communicate with UT-4DR interface it is necessary to know its IP address and port.
Default parameters of the interface are as follows:
IP address=192.168.0.38
Subnet mask=255.255.255.0
Default gateway=192.168.0.1
Administrator login: root
Administrator password: dbps
TCP port = 2101
It is assumed that mentioned above parameters will be changed in particular access control
installation, specifically IP address and administrator password. These parameters can be modified
by means of UT-4DR webpage opened with web browser.
Note: In order to connect with UT-4DR in local area network (LAN), the computer must be in the
same subnet. In case of UT-4DR with default IP address, the IP address of computer should be
192.168.0.xxx.

4.2 Configuration with PR Master software
After connection of UT-4DR to access controllers within RACS 4 system and to computer in
LAN/WAN, the installer can proceed with installation and configuration of PR Master software.
UT-4DR acts as Ethernet-RS485 communication interface with access controllers.
In order to create new subsystem with UT-4DR unit and to detect access controllers, it is necessary
to select the option Networks in the main window of PR Master software and then click the
button Add network. In the newly opened window (see fig. 5) in the field Communication
port select UT-4DR, in the field Server IP enter IP address of UT-4DR and in the field Server
Port enter TCP port of UT-4DR. Additionally in the field Interface it is possible to select if the
interface is operated in LAN or WAN which results in different levels of acceptable communication
delays. If Custom option is selected then communication delay can be specified manually.

In the next step close the window by means of OK button and in the Network properties
window click the button Controllers. In the newly opened window click the button Add in order
to detect all controllers connected to RS485 bus. The maximum number of PR series access
controllers connected to UT-4DR equals to 32 units and each controller connected to RS485 bus
must have unique address. Example of RACS 4 system is shown in fig. 6. Multiple UT-4DR
interfaces each in individual RS485 network (subsystem) can operate within single RACS 4 system.
Each UT-4DR interface must have individual IP address but they can use the same TCP port.
4.3 Configuration with Telnet
In order to log in to the UT-4DR, please type in the command line: telnet <device IP address>, e.g.
telnet 192.168.0.38. Then please log in as a default user (user: root, password: dbps). Then after
entering help command, a list of available commands shall be displayed.

Note: Procedure of connection with UT-4DR interface using Telnet protocol may vary depending on
used Telnet client application. In Windows Vista and Windows 7 Telnet client is disabled by default
and it has to be enabled prior to connection with UT-4DR.
4.4 Time synchronisation
UT4-DR interface can synchronize time of devices connected to its RS485 bus using selected NTP
server. Parameters of NTP server including time zone and daylight saving time can be configured in
Network tab during the configuration of the interface with web browser. When server address is
empty then suggested default address can be selected from the list. The latest synchronization is
logged in Network Statistics tab.
The interface synchronizes time with NTP server after restart, after TCP connection restoring and
periodically every 20 minutes after previous synchronization and then it sends time data on RS485
bus if no communication is detected on the bus i.e. when CPR32 controller is not connected and PR
Master software is not operated in Online Monitoring mode. Time synchronization with UT4-DR
interface can also be applied in RCP Master Time&Attendance system in standalone mode.
4.5 Memory Reset
Memory reset procedure erases current settings and restores default factory settings.
Memory reset procedure
•Terminate communication with the interface
•Place jumper on contacts according to fig. 8
•Restart the interface (press RESET button or switch power supply off/on) –triple blink of LED
STATUS (after 5 sec.) confirms that Memory Reset is finished
•Remove the jumper from contacts
•Restart the interface (press RESET button or switch power supply off/on)
•The UT-4DR shall switch to normal mode with default settings. Default settings of the UT-4DR
are specified in paragraph 4.1 Configuration with web browser.
